T0 @ZZ whom t may concern: v Be it known that we, WALTER L.

the county of'Norfolk and State of Massachusetts, have invented an Improvement in Eyeleting-Machineaof which the following de-v scription, in connection with the accompany' 'novel construction and arrangement of the operative parts whereby the distance between Y the eyelets set by the machine may be varied and also in an improved gage for the stock, or spreader, as it may be termed, whereby the distance of the eyelets from the edge of the stock may be varied to obtainthe spread or curvature of the line of eyelets as they are now commonly arranged in shoe-uppers. Y

The invention is hereinshown as applied to a machine constructed substantially as shown and described in Patent No. 581,855, granted to PerleyR. Glass May 4, 1897, in which thestock is punched and then advanced by an independent feeding device to the eyelet-setting devices, which then operate to set the eyelet in the hole at the end of the punch, andthe novel devices which embody the invention will be described in conjunction with such a machine, although itis .obvious that such devices might be applied to other machines without departing from the invention.

To vary the distance between adjacent ,eyelets as they are set in a line by the. machine, the punch, in accordance Wilhthe present Y invention, is adapted to be moved laterally v with relation to theeyelet-setting devices,

andthe feed movement is correspondingly adjusted, these'two vadjustments beingef.-

fected by common means, so as to maintain.

the proper relation,the distance between the punch and the eyelet setting devices obviously being thedistance which 'the stock-is required to be moved at each operation of the machine, this distance also being the distance' between the adjacent eyelets. In addition to the permanent adjustment, as it may be called, which may be effected to suit any particular class of. work which is to be done,

WHITTE-` MORE and PERLEY R. GLAss, of Quincy, in

the machine is further provided, in accordi ance with the invention, with means whereby the arrangement may be temporarily shifted from its permanently-adjusted position and thefeed correspondingly changed at the Will of the attendant in the operation of the machine, so that, if desired, there may be a greater distance between some of the eyelets set during'one complete run of the machine than there is between others, this variation being accomplished without stopping the machine or changing the permanent adj ustment.

The gage or spreader constructed in accordance with the invention comprises an arm or lever which is adapted to engage the edge of the stock and determine the position thereof relative to that of the devices which are to operate thereomthe said gage being controlled .by a cam which is adapted during a certain part of a complete run to be moved step by step automatically,thereb'y changing at each successive operation the position of the stock with relation'to the setting devices, so -as to produce the spread'or curve in the line of eyelets set. The gage and cam both travel, with the feeding device,which has a rectilinear movement produced bya swinging lever,

and the cam is provided with ratchet-teeth adapted to cooperate with one or the other of a pair of pawls to move the said cam in one direction or the other, the said pawls being mounted on the said lever, and'thereby moving on the arc of a circle and operating to advance the cam, which, as'stated, is mounted on the slide which moves in a straight line. The said pawls are so arranged, in accordance with the invention, that they canbe alternately thrown into engagement with the ratchet-teeth, so as to positively move the cam in either direction at the will of the operator.

The machine to-which the invention is herein shown as applied is substantially the same in general construction as that shown in the prior patent above referred to, themain operatin g parts being the punch-lever A, which carries the punch a, the setting devices B B2, and the feeding device for the stock, which comprises the slide C and the gripper member C2which are connected to and operated by the lever C3. In the usual operation of the machine the stock is iirst punched and as the punch rises is carried by the feed-slide C and gripper member C2 a distance equal to the distance between the punch and the setting devices, so that the hole made, by the punch is presented to the setting devices, which then operate to insert and set an eyelet. It' therefore both the punch and the set,- ting devices are to operate upon the stock and it is desired to set the eyelets at other than the normal distance apart, it is necessary to changethe distance between the punch and the setting devices and to correspondingly change the throw or extent of movement of the feed-slide.

As herein shown, the punch a is secured, as by a bolt or screw a?, in a carrier CL3, connected with, but laterally movable with relation to, the lever A. rlhe said carrier is normally pressed laterally into engagement with a pin b, which is longitudinally movable through the projection B3 of the frame which carries the upper eyelet-set B, so that the movement thereof will determine the lateral position of the punch with relation to that of The carrier a3 is supported and guided in its movement by means of a slotted plate a4, suitably secured to the face of a lateral extension A2 of the lever A, the said extension forming, in conjunction with the plate, an actuator or socket for the said carrier a3. The said carrier is provided with the slide a5 at the rear of the plate a4, whereby it is retained in the socket. 'lo keep the carrier normally in engagement with the pin b, it is acted upon by the spring a, which is shown as contained in an opening or bore A3 iu the lateral extension A2, the said bore com m unicating with the guideway or the slide a5 by means of a slot, into which extends a pin a7, connected with said slide to be acted upon by the said spring. For convenience in assembling the said spring is shown as held in position by means of a plate as, fastened to the end of the projection A2 to close the bore and support the end of the spring after it is in position. To adjust the position of the punch with relation to that of the setting devices, therefore, it is necessary only to provide means for longitudinally moving the pin b, this being accomplished by means of an 'arm b2, shown as clamped by means of a capscrew b3 to a rock-shaft b4, having a bearing along the side of the extension B3. The position of the said arm b2 may obviously be adj usted, if desired, with relation to the rockshaft by loosening the cap-screw b3 and again tightening the same after the proper adjustment has been effected. To operate the rockshaft, it is provided at its oppositeend with a lateral projection' or arm b5, adapted to be operated upon by an extension or lever arm c, mounted upon a hub or boss c2, from which extends an operating-arm o, connected, as by a rod c4, with an operating treadle or handle. (Not herein shown.) The said arm cis shown side and adapted to engage an enlargement h6 at the end of the arm b5, thereby constituting practically a universal joint, whereby the downward movement of the arm c in response to the movement of theoperating device causes a corresponding downward movement of the arm b5, whereby the arm b2 engages the pin Z) and pushes the same to the left, Fig. 2, thus increasing the distance between the punch and the setting devices. To correspondingly control the extent of movement of the feedslide C, the hub or boss c2 is shown as pro-A vided with a downward projection c5, having a beveled surface c6, which is adapte-d to be engaged by the lever C3 at the end of the movcment of said lever in response to its restoring-spring C4, Fig. 5, to produce the return movement of the feed-slide. That portion of the lever C3 which engages the beveled surface c6 is correspondingly beveled, it being obvious, therefore, that a movement of the projection c5 in the direction of the arrow, Fig. G, will admit of an increased movement of the lever C3 before it is stopped by the said projection, it being obvious, therefore, that when the hub c2 is rocked by lifting the arm c3 the result will be not only that the punch is moved farther away from'the eyelet-setting devices, but that the lever C3 will have an in` creased movement before it gripsthe stock, and consequently will carry the same an 1ncreased distance in its forward movement, the

limit of which is constant, being determined by the cam C, which produced the forward or positive movement of the lever. 3y the proper relative adjustment, therefore, of the beveled surface c and the arm h2, which controls the punch, the distance between the adjacent eyelets may be varied at will. As thus far described, the variation has been shown as accomplished by the upward movement of the arm c3, the normal position of the said arm being controlled by the stop projection c, formed on the frame, the'said stop projection being engaged by a portion of the hub c2 or parts movable therewith. In order, therefore, to provide means for primarily ad justing the position of the punch and corresponding throw of the feed, it is necessary only to vary the normal position of the said hub c2, and to this end the said hub is shown as provided with a projection c7, having an adas a substantially cylindrical shell open at one loo' IIC

justing-s'crcw cs, the end otwhich engages the projection c aforesaid. \Vhen, therefore, it is desired to permanently change the normal relation of the punch to the eyelet-setting devices, it is necessary only to adjust the said screw 08. When, however, a portion of the eyelets are to be set at a 4certain distance apart and others during the same run of the machine at a greater distance apart, it is desirable to insure uniformity, and to this end the hub c2 is further provided with a projection 070, corresponding to the projection c7, and the adjusting-screw C80, which is adapted to engage the opposite side of the stop c6 and limit the movement of the hub in response to the movement of the treadle or other actuating device. This movement may also be adjusted, and if it is desired to render the treadle inoperative when it is not desired to use the same and all of the Work is to be uniform the hub and the parts controlled thereby may be locked in any desired position by properly adjusting the screws cB-and C80, so that they both engage. with the projection c6 when the hub c2 is in the position desired.

The gage for the stock, or spreader, as it may be called, is herein shown as consisting of 'a lever-arm d, pivoted at d2 upon the feed-slide C, the said lever-arm having an engaging portion d3, adapted to engage and position the edge of the stock, as best shownin Fig. 6. as consisting of a slide-block secured to the arm d by means of a 'nut d4, so that it may be adjusted with relation thereto. The movement Vof the arm d on its pivot will change the. position of the engaging portion d3 and correspondingly change the position of the stock with relation to the punch and setting devices. To spread the eyelets, therefore or set the same on a curved line, a step-by-step movement of the gage is produced, whereby the position thereof is changed after each eyeleting operation and priorto the next operation, so that the next eyelet is set in a slightly-different position with relation to the edge of the stock. This is accomplished in Aaccordance with the present invention by means of a cam e, adapted to engage an arm or extension d5 of the gage d, .the said cam which are pivoted at f upon the feed-lever C3A or an extension therefrom, so that either one of said pawls may be thrown into engagement with its cooperating teeth, the other pawl at the same time being out of engagement with the other teeth. -Since the pawls f2 and f2() are mounted, as stated, upon the lever C3, their path of travel will be on the arc of a circle and the path of travel of the cam as it is carried by the Afeed-slide will be rectilinear, so that `the relativemovements will cause the pawl as it travels in one direction to ride over and catch a tooth and as it travels in the other direction torotate the cam a certain dis- The said engaging portion d3 is shown tance, the teeth being of such size that the cam will be advanced the distance between two teeth at each feed movement. The teethare arranged on op osite sides of the cam, so that when one paw is thrown into engagement with the corresponding teeth it will move the cam in one direction, and if the other pawl is thrown into engagement with its corresponding teet-h it will move the cam inthe opposite direction. The number of teeth at each side of the cam corresponds to the number of eyelets which are to be spread or set in a different position yfrom the main line of eyelets,

and beyond the teeth at each side there is a blank space along which the pawl travels idly back andforth in the feed movement without producing any further movement of the cam.

' In the position shown in full lines, Fig.- 6, the shoe-upper D is placed in the machine with its edge against the gage,which,as shown, is inits farthest position away from the punch and setting, devices which operate upon the stock, so that the first hole eyeleted will be at the maximum distance from the edge. The pawl f2 is then in engagement with'the teeth e2 and in the feed movement will ride over one of the said teeth, the return movement advancing the cam toward the dottedline position, so that' the gage approaches` the punch and setting devices, moving the stock until the edge thereof is nearer the said devices, this operation continuing, so that IOO each eyelet is nearer the 'edge of the stock than the preceding one, until the dotted-line position is reached, the pawl then having passed beyond the last tooth, so that it produces no further movement of the cam. The

4operation of the machine then continues, with IIO The first shoe-upperhaving been*V lower end, where the eyelets are spread, to-

ward its upper end, the next shoe-upper-will have to be inserted so as to travel from its upper toward its lower end', so that the gage in its dotted-line position will properly position the stock at the beginning of the operation. Toward the end of this operation, however, the eyelets must be again spread, it being-essential, therefore, that the gage should move step by step from the dotted-line position back to the full-line position. To this end at the proper period thev pawls are -shifted by the operator so that the pawl f20 coperates with the teeth @20, thus restoring the cam step by stepto the full-line position shown. The gage is shown as provided with'a spring d, whereby it is held in engagement with the cam and restored' in the reverse movement of said cam. Tqshift the pawls and retain them in either operative position, the said pawls retaining-spring being shown as adapted to move the pawls in either direction from a central or neutral position. For this purpose the spring is shown as connected at one end to the part which carries th'e pawls and at the other end to a partl of the machine which is beyond the axis upon which the pawls move, so that a movement in either direction toward a middle or neutral position will strain the spring, which will operate to move the pawl in the opposite direction as soon as the spring crosses the axis. To render the operation of the spring more positive, one end of the same is herein shown as connected to an arm or projection f6 from the part to which the pawls are connected and at its opposite end to a supplemental arm f7, pivoted on the extension f5,in which the pawls are supported, the two arms being adapted to intermcsh, as by teeth fm 011 the arm f and a projection j on the arm f7, so that a movement of the end of the arm f in one direction will produce a corresponding movement of the arm f7 in the opposite direction, the said arms being so arranged that when the pawls are in a neutral position the arms are in alinement with each other and with their pivots, it being obvious, therefore, that the tendency of the spring will be to move them in either direction from the central or neutral position. Vhen the pawlf2 is in its operative position, as shown, the movement of the feed-lever will tend to carry the same to the left, Fig. 6, and to prevent the spring f4 from acting to shift the pawls the feed-slide is provided with a stop fs to engage the pawl fzand retain the same in engagement with the teeth of the cam. By this construction and arrangement the gage is positively moved in each direction, and the operating device for the gage only needs to be shifted once during the operation of the machine for each pair of uppers. The shifting is easily accomplished, requiring only a touch of the finger, so that it is practicallyimpossible to fail to properly operate the machine.

The cam and teeth may be secured to the feed-slide in any suitable or usual way, the said feed-slide being herein shown as provided With a stud e3, the cam and teeth being made in one piece, having a bearing on said stud, and being held in position by means of a serer c4, Fig. 10. The lower surface of the said cani is preferably provided with a series of radial grooves e, cooperating with a springtongue c, connected with the feed-slide, the said tongue, in conjunction with the grooves, operating as a centering or retaining device to prevent the cam from overth rowing when operated by the pawls.
